03-Understanding Spring Bean Factory

Spring is a container of beans, it behave as a factory of beans, like

-          Tomcat is a servlet container

-          Tomcat creates servlet objects which are required to run an application.

Spring has as many numbers of objects you want and all these are managed by spring container

Mange in the sense, it handles instantiation of the objects, whole life cycle of the object and it handles destruction of those objects.

You can have objects outside the spring container, but adding the objects inside the spring container gives lot of advantages.
